A negative test result would be a normal gag reflex.

如表现为正常的咽反射，则为阴性。

These gag reflexes can be compromised, however, by drug and alcohol abuse, brain injuries, or swallowing issues.

然而，药物和酒精滥用、脑损伤或吞咽问题可能会影响这些咽反射。

[Tom] I think my gag reflex has been activated by a thought!

- [Tom] 我想我的呕吐反射被一个念头激活了！

Teeth plaCement, jaw stress, suCtiOn, and gag reflex, all the while bObbing up and dOwn, mOaning and trying tO breathe. Easy?

牙齿要放对位，下颚紧绷 吸吮和快室息的感觉，在上上下下之际 还要一边呻吟呼吸，简单吗？

Doctors also check for a cough and gag reflex and perform an apnea test, where the ventilator is turned off and a live person would reflexively make an attempt to breathe, a brain dead person would not.

医生还会检查咳嗽和呕吐反射， 并进行呼吸暂停测试，此时呼吸机会关闭， 活人会反射性地尝试呼吸， 而脑死亡的人则不会。
